The 2015 French Open is still months away, but the most dominant player in the tournament’s recent history is expected to win another title this year. He might not be the top-ranked player in the world, but Rafael Nadal is the betting favorite to win the second Grand Slam event of 2015.

Nadal leads all players with 11/8 odds of winning the title. Since 2005, Nadal has failed to end the French Open victorious just once. In 2009, Roger Federer beat Robin Soderling in the finals, while Nadal lost to Soderling in the fourth round. Last month, he lost to the No.7 seed Tomas Berdych in the quarterfinals of the 2015 Australian Open.

Novak Djokovic ranks No.1 in the world, and despite Nadal’s dominance on clay, he’s been given a good chance to challenge for the title. At 3/2 odds, Djokovic is the second favorite, looking to win his second Grand Slam of 2015. He defeated Andy Murray in the finals of the Australian Open, and lost to Nadal in last year’s French Open Final. It’s the only Grand Slam tournament that Djokovic has never won.

In addition to Djokovic, Federer is also ranked ahead of No.3 Nadal in the ATP rankings. However, he isn’t given nearly the same chance of winning the tournament. He’s behind Nadal, Djokovic and Stan Wawrinka with 20/1 odds.

Andy Murray also has 20/1 odds, after losing to Djokovic in the finals of the Australian Open. The “Big Four” of Murray, Djokovic, Federer and Nadal have dominated the Grand Slams over the last decade. Since the start of 2004, only five Grand Slam tournaments have been won by players outside of the "Big Four."

In 2014, only two of the Grand Slams were won by the “Big Four.” Wawrinka took home the title at the Australian Open, and Marin Cilic ended the year with a victory at the U.S. Open. Cilic’s odds at the French Open are 40/1.
